U2 (Bono)

Bono, U2's lead singer, has spent the last several years urging Christians to support the human rights causes. While the Irishman has been eager not to call himself a Christian (he says he’d “like to be” one), he nevertheless became for many Christians a symbol of integrating art, faith, and global engagement.

Greg Garrett, a professor at Baylor University and author of We Get to Carry Each Other: The Gospel According to U2, suggests Christian rock has become a toxic phrase in pop “for a good reason." (Houston Chronicle)
